Log-concavity of the Fennessey-Larcombe-French Sequence

Arthur L. B. Yang, James J. Y. Zhao

Published 2015-03-07Version 1

We prove the log-concavity of the Fennessey-Larcombe-French sequence based on its three-term recurrence relation, which was recently conjectured by Zhao. The key ingredient of our approach is a sufficient condition for log-concavity of a sequence subject to certain three-term recurrence.
